Bussmann series FRS-R 600 V Class R 65-600 A fuse data sheet no. 1018
Feature → Business Impact → Application: Time-delay, dual-element design enables selective protection, reducing nuisance trips while maintaining fast fault clearance. This translates to higher line uptime and longer motor life in high-inrush environments such as conveyors and presses, making it ideal for automation panels in manufacturing. Feature → Business Impact → Application: High interrupt rating—200 kAIC at 600 Vac (and 20 kAIC at 300 Vdc)—provides robust fault clearing for large power feeds, minimizing arc fault energy and equipment damage in switchgear and motor control centers. Feature → Business Impact → Application: Blade-end connections and standard packaging simplify “drop-in” replacement in existing Bussmann RK5 installations, reducing commissioning time and enabling quick upgrades in OEM panels. Feature → Business Impact → Application: Time-delay operation with a 10-second response at 500% overload supports coordinated protection strategies in motor starters, drives, and automation controllers, improving safety margins and serviceability. Feature → Business Impact → Application: Non-indicating indicators reduce panel clutter while requiring integration with external health monitoring, helping maintain compact layouts in space-constrained enclosures.

FAQs
FRS-R-110 uses blade-end x blade-end connections and fits standard RK5 fuse holders. Its length is 9.63 in with a 1.6 in width, making it compatible with common control panels and switchgear housings. Ensure correct alignment and secure mounting to maintain reliable fault clearing.
The fuse is rated for 110 A with a voltage rating of 600 Vac / 300 Vdc. It provides an interrupt rating of 200 kAIC at 600 Vac and 20 kAIC at 300 Vdc, and it operates as a time-delay, dual-element current-limiter suitable for inrush-heavy loads.
Yes. Its time-delay operation and high interrupt rating support motor protection in drives, starters, and automation panels. The RK5 class design offers protective coordination to minimize downtime while preventing short-circuit damage in demanding industrial environments.
The FRS-R-110 is CE marked. Compliance information and RoHS-related resources are available through Eaton’s tools to support global safety and regulatory requirements in your region.
Being a non-indicating fuse, it may require external health monitoring in the control system. The fuse’s high inrush tolerance, reliable fault clearing, and RK5 coordination can lower downtime and extend motor and circuit life, delivering a favorable total cost of ownership in automation projects.
